Problems solved by technology

[0005] These structures, although capable of providing hot gas in a fuel cell system, generally do not guarantee complete conversion of all undesirable residues contained in the exhaust gas of the fuel cell, such as residues of hydrocarbons when gas generation systems are used, such as JP as described in the abstract, or the residue of hydrogen when using hydrogen storage, as described in the DE literature

Embodiment Construction

[0022] figure 1 and 2 Two different configurations of a fuel cell system 1 are described in , preferably, but not exclusively, for the arrangement according to the invention for supplying hot exhaust gases. Forming the core of the fuel cell system 1 is a fuel cell 2 configured, for example, as a PEM fuel cell stack. In this case, the cathode chamber 3 and the anode chamber 4 of the fuel cell 2 are separated from one another by a proton-conducting membrane 5 . Oxygen from the air is typically used as oxidizing agent for operating the fuel cell 2 , for which the air is fed into the cathode space 3 via the air supply device 6 . The anode chamber 4 is supplied with hydrogen or a gas containing hydrogen. In the exemplary embodiment shown here, the anode space 4 of the fuel cell 2 is to be supplied with hydrogen from a pressurized gas store 7 . The hydrogen stored at high pressure in this pressurized gas accumulator 7 is supplied to the anode chamber 4 via a valve arrangement 8 ...

Abstract

A device serves for providing hot exhaust gases for driving a turbine (24). The device has a burner (17), the combustion zone (23) of which is integrated directly on or in the gas inlet (turbine casing 29) of the turbine (24). The burner (17) is fed at least one combustible gas or gas mixture. According to the invention, the combustion zone (23) comprises an open-pored material with a high specific surface area.

Description

technical field [0001] The invention relates to a device for supplying hot exhaust gas for driving a turbine and to the use of such a device. Background technique [0002] In principle, it is known to operate turbines with hot exhaust gases from combustion. US 2002 / 0157881 A1 describes a structure in which the vehicle is supplied with electrical energy via a turbine and a generator driven by a burner. What is now special in the US publication is that the burner is integrated in the turbine or turbine inlet housing. The burner itself is here designed as a flame burner, which provides the highest possible temperature for operating the turbine. Now, the disadvantage in this construction is that this burner produces undesirable substances, such as NO x Strong emissions of emissions. Thus, in the US publication there is provided an alternative catalytic reactor in the form of an exhaust gas catalytic converter which converts the residue after depressurization of the hot exhau...
